Controllers

• HLS 16
  	HLS 16 is a 1-step floor heating / cooling controller for individual room temperature controlling.

  ---

• HLS 21
  	HLS 21 is a 2- stage room temperature controller, for heating and cooling, using thermal (PWM) actuators.

  ---

• HLS 21-EXT
  	HLS 21-EXT is a 2- stage room temperature controller with external NTC10 temperature sensor, for heating and cooling, using thermal (PWM) actuators.

  ---

• HLS 33
  	HLS 33 is a room temperature controller with 2- or 3-stages. One stage is for heating and up to two stages for cooling. These controllers can be used with 0-10V, 3-point or with thermal (PWM) actuators.

  ---

• HLS 33-EXT
  	HLS 33-EXT is a room temperature controller with 2- or 3-stages. One stage is for heating and up to two stages for cooling. These controllers can be used with 0-10V, 3-point or with thermal (PWM) actuators.

  ---

• HLS 34
  	HLS 34 is a room temperature controller with RS-485 connection for (RTU) modbus. By using display and push buttons operator may adjust set point and control fan speed. Commission can be made by using internal push buttons, or by using a master unit with settings made in advance. E.g. occupancy or CO2-sensor can be used with HLS 34.

  ---

• HLS 35
  	HLS 35 is specifically designed for individual room floor heating/cooling applications. The controller has built-in RS-485 channel for Modbus communication.

  ---

• HLS 44
  	HLS44 is an advanced multifunctional controller specifically designed for individual room temperature and zone control applications. Controller has a built-in, galvanic isolated RS-485 channel for communication via Modbus and it can be connected to any supervisory Modbus RTU software / system.

  ---

• HLS 44-V
  	HLS44-V is an advanced multifunctional controller specifically designed for individual room temperature and light control applications. Controller has a built-in, galvanic isolated RS-485 channel for communication via Modbus and it can be connected to any supervisory Modbus RTU software / system.

  ---

• HLS 44-SER
  	HLS 44-SER is a tool for commissioning HLS 44 and HLS 44-V controllers. By using this tool the commissioning is fast and you may rely on that the settings are as planned.

  ---

• HS 2.2
  	HS 2.2 is a universal controller made for HVAC applications. It may be used for controlling e.g. pressure, differentail pressure, temperature or illumination level. Display is possible to scale according to the measurement.

  ---

• PDS 2
  	PDS 2 is a universal controller, which can be configured to 2 different program modes (VENT or HEAT). Mode “VENT” works as a P/PI controller for air-conditioning systems and warm domestic water supply. Mode “HEAT” works as an outdoor compensated temperature regulation for the heating system.

  ---

• PDS 2.2
  	PDS 2.2 is a universal controller, which can be used for controlling pressure, differential pressure, humidity and temperature. Input of PDS 2.2 is for a 0-10V signal. Actuators may be 0-10V controlled and 3-point or thermic actuators. Commissioning and settings will be made by using built-in display and touch sensible buttons.
